Due to the backward conditions of the product in the past, such as high energy consumption and low thermal efficiency. Therefore, in view of the above-mentioned defects in the current prior art, it is necessary to conduct research to solve the defect of low thermal efficiency of the existing large cooker.

Utility model content

The utility model provides a waste heat recovery type large stove, which solves the problem of low thermal efficiency existing in the existing large stove.

The technical scheme adopted by the utility model is:

A waste heat recovery type large pot stove includes a stove system and a water circulation system, wherein the stove system includes a stove body frame, a pot, and a flue, and a burner is arranged below the pot; the water circulation system includes a water tank and a first water circulation coil. The water tank is an automatic water replenishment and heat preservation water tank; the water tank includes a first water inlet, a second water inlet, a first water outlet and a second water outlet;

The first water circulation coil is arranged on the inner wall of the frame of the stove body, and the lower end of the first water circulation coil is communicated with the water outlet end of the water-air linkage valve; the upper end of the first water circulation coil is communicated with the second water inlet through a water pipe;

The first water inlet is located at the top of the water tank, and the first water outlet and the second water outlet are located at the bottom of the water tank;

The water inlet end of the water-air linkage valve is communicated with the first water outlet through a water pipe, and a circulating water pump is arranged on the pipeline between the water-air linkage valve and the first water outlet;

A check valve is arranged between the upper end of the first water circulation coil and the water tank; the second water outlet is connected to the water system through a water pipe. The water in the water tank is set up to store water, and the water in the water tank is passed through the furnace of the large stove through the circulating water system. The water in the first water circulation coil is heated, and the heated water is returned to the water tank. Therefore, the water in the water tank can be heated by circulation. The water tank can be selected to automatically replenish water and keep warm. When the water volume of the water tank decreases, the water tank can automatically replenish water. , the heat preservation water tank can keep the heated water warm and enhance the practicability. When using it, a water valve can be set on the water supply pipeline to avoid the water tank supplying water while using the water tank water and reducing the water temperature of the water tank; The heat is dissipated, and its heat conversion rate is low. Therefore, the excess heat is converted into the water in the water tank through the first water circulation coil, and provided to other places where hot water is used, which greatly increases the capacity of the stove. The heat transfer rate can also save gas and hot water, and its practicality is high.

Further, the water circulation system further includes a second water circulation coil; one end of the second water circulation coil is connected to the upper end of the first water circulation coil, and the other end of the second water circulation coil is communicated with the second water inlet; the second water circulation coil A water circulation coil is located within the flue. Considering that all large stoves are equipped with flues, and the internal temperature of the flues is also very high, especially the end of the flue close to the furnace, therefore, by arranging the second water circulation coil inside the flue, the water from the first water circulation plate The water heated by the pipe is passed into the second water circulation coil to continue heating for heat recovery, and then the water is returned to the water tank by the second water circulation coil; thus, the waste heat in the flue is recovered, the heat conversion rate is increased, and the utility model is improved. sex.

Further, a booster pump is arranged on the pipeline connected to the second water outlet. By arranging a booster pump on the pipeline of the water end, it is ensured that the water tank can be supplied with water even when the water tank is on the same level as the water outlet or lower than the level of the water outlet, thereby increasing the practicability.

Further, the water tank is provided with a temperature sensor; the temperature sensor includes a display panel and a temperature sensing probe, the temperature sensing probe is located inside the water tank; the display panel is located outside the water tank. By setting the temperature sensor with display function to detect the water temperature in the water tank, you can use the water with reference to the water temperature.

Further, the water tank is located above the side of the cooktop frame and is disposed adjacent to the flue. Considering that the flue of the cauldron is one side of the principle operation position, setting the water tank at the flue will not hinder the operation. At the same time, the high temperature environment of the flue makes the ambient temperature of the water tank relatively high, which is the slow heat dissipation of the water tank. The thermal insulation effect of the water tank is better, and the practicability is improved.

Further, the water tank is provided with a longitudinal groove, and the flue is located in the groove. Since the flue will occupy part of the upper space of the stove frame, the space on both sides of the flue is almost useless. Therefore, the design of the water tank to wrap the flue can maximize the use of the wasted space on both sides of the flue. The package can maximize the use of flue heat to maintain the temperature of the water tank and reduce heat loss.

Further, the bottom of the water tank is provided with load-bearing feet. In order to increase the capacity of the water tank, independent water tank bearing feet are provided to support the water tank to improve the stability of the water tank.

Further, the length of the water tank is the same as the length of the stove body frame, and the width of the water tank is 20-30 cm. For the sake of beauty, the length of the water is designed to be the same as the length of the cooktop frame.

Further, the second water outlet is connected with a hot water faucet through a pipeline, and the hot water faucet is located on the side wall of the stove frame and above the pot.

Further, a refractory material heat insulating layer is arranged in the furnace of the stove body frame. The heat insulation layer of the refractory material is used to prevent too much heat loss inside the furnace, and it can also prevent the frame of the stove body from being seriously heated, which affects the operation.
